Nuts & Bolts
Our ABS flange nuts & bolts are supplied as complete, ready-to-use fixing sets, specifically selected for secure and reliable flange joint assembly. Whether you are installing a standard industrial ABS system or working in a more aggressive environment, we stock two high-performance options to suit different site conditions: Bright Zinc Plated (BZP) grade 8.8 steel and 316/A4 stainless steel.
Each set includes everything required for a proper flange connection:
- 4 × Hexagon head bolts (DIN 931 threaded or part-threaded)
- 8 × Washers
- 4 × Nuts
Designed for use with ABS flanges, backing rings and gaskets, these bolt sets provide consistent clamping force and long-term joint integrity across a wide range of applications.
Bright Zinc Plated (BZP) Grade 8.8 Bolt Sets – Strength & Cost Efficiency
BZP bolt sets are manufactured from high-tensile grade 8.8 steel, offering excellent mechanical strength for general engineering and pipe flange installations. With an ultimate tensile strength of 800 N/mm² and a yield stress of 80% of UTS, these fixings are ideal where high loading capacity is required.
The bright zinc plated coating adds a protective layer against light corrosion and weathering, making these bolts suitable for:
- Indoor installations
- Dry plant rooms
- General industrial environments
- Mechanical and structural assemblies
Why choose BZP?
- High structural strength at a lower cost
- Ideal for controlled, dry environments
- Widely used for standard ABS flange bolting
- Reliable performance for general pipework systems
Stainless Steel (316 / A4) Bolt Sets – Maximum Corrosion Resistance
Stainless steel bolt sets are manufactured from 316/A4 grade stainless steel, offering exceptional resistance to corrosion, even in harsh, wet or chemically aggressive environments. Unlike zinc-plated fixings, stainless steel will not suffer coating breakdown, making it the preferred solution for long-term durability.
These sets are commonly used in:
- Marine and coastal installations
- Chemical processing areas
- Food and beverage environments
- Outdoor pipework systems
- Hygienic or wash-down areas
Why choose Stainless Steel?
- Outstanding resistance to rust, moisture and chemicals
- Ideal for outdoor and wash-down environments
- Long service life with minimal maintenance
- Food-grade and hygiene-suitable material
- Excellent joint reliability in demanding installations
